CHURNlNG-MACHINE.

SPECIFICATION orming p o Let a e 785,775, dated March 28, 1905.

To all whom it may concern:

Be it known that I, ORIEN S. STRIGKLAND, a citizen of the United States, residing at Cooper, in the county of Delta and State of Texas, have invented anew and useful Ohurning-h Iachine, of which the following is a specification.

This invention relates to certain improvements in churns, and more particularly to mechanism for imparting a reciprocator'y motion to the churn-dasher.

The object of the invention is to improve, simplify, and cheapen the construction of devices of this character whereby the churning operation is greatly facilitated and the labor involved reduced to a minimum.

A further object of the invention is to provide a pair of slotted crank-arms having pitman-rods adjustably connected thereto and to the upper portion of the churn-dasher, so that by adjusting the pitman-rods longitudinally of said crank-arms the vertical movement or throw of the dasher may be regulated at will.

In the accompanying drawing, forming a part of this specification, and in which corresponding parts are indicated by like numerals of reference, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements herein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

The churn-operating mechanism forming the subject-matter of the present invention is mounted on a supporting-frame 5, substantially rectangular in shape, as shown, and formed of wood, metal, or other suitable material.

The supporting-frame consists of a pair of longitudinal beams 6 and 7, connected in any suitable manner by cross-beams 8, said frame being supported by divergent legs 9, the upper ends of which are recessed, as indicated at 10, for the reception of the frame. Arranged parallel with the longitudinal beam 7 is a similar beam 11, said beams being spaced apart by blocks 12, thereby defining a pocket or housing 13, in which is mounted a train of gear forming a part of the churn-operating mechanism.

vided with longitudinally-disposed slots or re- I cesses 21, and adjustably mounted in said slots are pitman-rods 22, the upper ends of which are connected, through the medium of a collar or sleeve 23, to the churn-dasher 24:.

The pitman-rods 22 are ad justably connected to the crank-arms by means of bolts 25, which pass through the slots 21, so that by moving the pitmen longitudinally and tightening the clamping-nuts 26 said pitman-rods may be adjusted to vary the throw of the churn-dasher. The upper ends of the pitman-rods are bifurcated, as indicated at 27, and are pivoted to oppositely-disposed ears or lugs 28 on the colla'r 23, the latter being adjustable on the dasher and secured in fixed position by a set-screw '29. The dasher, which may be of any approved construction, reciprocates in a guiding-bracket 30, secured to the longitudinal beam 6, and arranged at the rear of said dasher is an angularly-disposed supporting-table 31, adapted to receive the vessel containing the cream to be churned. The table is provided with one or more cleats 32 for preventing accidental displacement of the creaming vessel, said table being centered with respect to the dasher by means of a vertical slot 33, which engages the transverse shaft of the mastergear 14:, as shown.

The device may be operated by a motor or other suitable source of power by mounting a pulley on the shaft of the master-gear 14; but in the present instance I have shown the said shaft provided with a terminal crank 84 for operating the machine manually.

From the foregoing description it is thought that the construction and operation of the machine will be readily understood by persons skilled in the art and further detailed description thereof is deemed unnecessary.

Having thus described the invention, what is claimed is 1. The combination with a supporting frame, of a reciprocating dasher, a pair of shafts journaled in the frame and each provided at one end with a pinion and at the other with a slotted crank-arm, a collar adj ustably secured to the dasher, pitman-rods having their upper ends pivoted to the collar and their lower ends adjustably secured to said slotted crank-arms, means for guiding the dasher, and an intermediate master-gear meshing with said pinions for reciprocating said dasher.

2. The combination with a su1i)p0rtingframe, of a reciprocating dasher, a pairof shafts journaled in the frame and each provided at one end with a pinion and at the other with a slotted crank-arm, a collar provided with oppositely-disposed ears or lugs adjustably secured to the churn-dasher, pitlnan-rods having their upper ends pivoted to said ears or lugs and their lower ends adjustably scoured to said slotted crank-arms, a mastergear meshing with one of the pinions and an intermediate gear meshing with the mastergear and the opposite pinion.

3. The combination with a supportingframe having its longitudinal side beams spaced apart to form a housing, a main shaft journaled in the frame and provided with a master-gear mounted for rotation in said housing, a pair of auxiliary shafts arranged one on each side of the main shaft and provided with terminal slotted crank-arms, a reciprocating churn-dasher, pitman-rods adjustably secured to the slotted crank-arms and pivotally connected to the upper end of the dasher, pinions secured to the auxiliaryshafts and rotated by the master-gear, and a table provided at its base with vessel-supporting means and having an angularly-disposed arm extending in a vertical plane at the rear of the dasher and provided with a terminal slot adapted to receive the main shaft.

in testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.
